With a Z-score of -0.72 (23.6th percentile), this represents normal volume ; hippocampal volume measures 6,941 mm³, 8.2% below the reference mean. With a Z-score of -0.80 (21.3th percentile), this represents normal volume ; whole brain volume measures 1,025,640 mm³, 5.0% below the reference mean. With a Z-score of -0.65 (25.9th percentile), this represents normal volume ; entorhinal cortex volume measures 4,211 mm³, 2.7% above the reference mean. With a Z-score of 0.18 (57.2th percentile), this represents normal volume ; fusiform gyrus volume measures 17,780 mm³, 5.6% below the reference mean. With a Z-score of -0.48 (31.6th percentile), this represents normal volume ; middle temporal gyrus volume measures 20,471 mm³, 4.1% below the reference mean.

  "gpt_diagnosis": "Reasoning: All brain volume measures (ventricular, hippocampal, whole brain, entorhinal cortex, fusiform gyrus, and middle temporal gyrus) fall within normal ranges based on Z-scores and percentiles. Cognitive assessments (MMSE: 30, MoCA: 28) are also within normal limits, indicating no significant cognitive impairment.  \n\nDiagnosis: CN (Cognitively Normal)  \nConfidence: High",
